So I am going to offer some advice to these NBA free agents. My advice to Kyrie is to not got to the Lakers. You won't be happy being 2A or 2B with Butler. I think LA would be a good place for Butler. Kawhi Leonard? Go to the Clippers.
As far as what Kyrie should do? I actually think the best thing for him would be to pair up with Durant. Durant would be the best player in my mind but Kyrie could be the more popular one or the more promoted one. I don't think Durant minds sharing the spotlight. For Kyrie, he could be playing with a top player while still getting plenty of spotlight. Best of both worlds.
Now if Boston can get Davis, Boston would be a good spot for Kyrie too, for many of the same reasons, although I think Durant takes him farther than Davis (assuming all else equal).
NBA stars never listen to me though. It would not surprise me if Kyrie and Durant both did something dumb.
